Guidelines for Decontamination of Facilities and Equipment (July 1982 Revision)

HPPOS-044 PDR-9111210197

See the memorandum from R. E. Cunningham to G. Page (and others) dated July 22, 1982. The memo provides NMSS revision of "Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source, or Special Nuclear Materials."

More than one branch of the Division of Fuel Cycle and Material Safety have been using a document titled, "Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source, or Special Nuclear Materials." There are, however, two versions of this document, dated November 1976 and June 1980, that have slight differences in wording but not in technical content.

In order to provide a single document that can be used uniformly by all branches of the Division, the version dated June 1980 was revised, and this revised version, dated July 1982, should be used by all branches of the Division until a subsequent revision is required.

A copy of the July-1982 revision is provided as an enclosure to the memorandum. The instructions in the report specify the radionuclides and radiation exposure rates which should be used in decontamination and survey of surfaces or premises and equipment prior to abandonment or release for unrestricted use. The limits in Table 1 of the report do not apply to premises, equipment, or scrap containing induced radioactivity for which the radiological considerations pertinent to their use may be different. The release of such facilities or items from regulatory control is considered only on a case-by-case basis.
